Project description:The oocytes found within the primordial follicles of mammalian ovaries remain quiescent for months to years until they receive the appropriate signals to undergo the primordial to primary follicle transition and initiate folliculogenesis. The molecular mechanisms and extracellular signaling factors that regulate this process remain to be fully elucidated. The current study investigates the mechanisms utilized by anti-Müllerian hormone (AMH; i.e. Müllerian inhibitory substance) to inhibit the primordial to primary follicle transition. Ovaries from 4-day-old rats were placed into organ culture and incubated in the absence or presence of AMH, either alone or in combination with known stimulators of follicle transition, including basic fibroblast growth factor (bFGF), kit ligand (KITL), or keratinocyte growth factor (KGF). Following 10 days of culture, the ovaries were sectioned, stained, and morphologically evaluated to determine the percentage of primordial versus developing follicles. As previously demonstrated, AMH treatment decreased primordial to primary follicle transition. Interestingly, AMH inhibited the stimulatory actions of KITL, bFGF, and KGF. Therefore, AMH can inhibit the basal and stimulated development of primordial follicles. To investigate the mechanism of AMH actions, the influence AMH has on the ovarian transcriptome was analyzed. AMH treatment when compared with controls was found to alter the expression of 707 genes. The overall effect of AMH exposure is to decrease the expression of stimulatory factors, increase the expression of inhibitory factors, and regulate cellular pathways (e.g. transforming growth factor beta signaling pathway) that result in the inhibition of primordial follicle development. Analysis of the regulatory factors and cellular pathways altered by AMH provides a better understanding of the molecular control of primordial follicle development. Experiment Overall Design: RNA samples from two control groups (pooled untreated cultured ovaries) are compared to two treated groups (pooled cultured ovaries treated with AMH)

Project description:Explore in vivo ovarian follicle transcriptomics from primordial follicles to the antral stage. Ovarian follicles were isolated from CD-1 mice. Entire ovaries were collected at post-natal day 3 and day 4 to collect primordial follicles. Primary follicles (70-90 µm in diameter), two-layered secondary follicles (100-130 µm), multi-layer secondary follicles (150‒180 µm), and pre-antral follicles (200‒300 µm) were mechanically isolated from post-natal day 10, 12, 16, and 18 ovaries, respectively. Antral follicles (400‒600 µm) were mechanically isolated from pregnant mare serum gonadotropin (PMSG)-treated mice ovaries at post-natal day 20. Follicles were then aspirated and combined per ovarian follicle maturation stage (e.g., primary, two-layered secondary). Three different samples were collected from each pooled follicular stage for transcriptomic analysis. RNA was purified and hybridized in MouseRef-8 v2.0 Expression BeadChip Kit (Illumina, San Diego, CA), as previously described (Skory, Bernabe et al., 2013).

Project description:Reconstituted Ovaries (rOvaries) represent an important method for in vitro derivation of gametes. The beginning of this process requires differentiation of mouse induced pluripotent stem cells (iPSCs) into Epiblast Like Cells (EpiLCs) followed by 6 days of differentiation as spheres containing PGC-Like Cells (PGCLCs) and somatic cells. Here, we characterize the cells in the differentiated spheres at day 6 of differentiation.

Project description:In mammalian females, quiescent primordial follicles serve as the ovarian reserve and sustain normal ovarian function and egg production via folliculogenesis. The loss of primordial follicles causes ovarian aging. Cellular senescence, characterized by cell cycle arrest and production of the senescence-associated secretory phenotype (SASP), is associated with tissue aging. In the present study, we report that some quiescent primary oocytes in primordial follicles become senescent in adult mouse ovaries. The senescent primary oocytes share senescence markers characterized in senescent somatic cells. The senescent primary oocytes were observed in young adult mouse ovaries, remained at approximately 15% of the total primary oocytes during ovarian aging from 6 months to 12 months, and accumulated in aged ovaries. Administration of a senolytic drug ABT263 to 3-month-old mice reduced the percentage of senescent primary oocytes and the transcription of the SASP cytokines in the ovary. In addition, led to increased numbers of primordial and total follicles and a higher rate of oocyte maturation and female fertility. Our study provides experimental evidence that primary oocytes, a germline cell type that is arrested in meiosis, become senescent in adult mouse ovaries and that senescent cell clearance reduced primordial follicle loss and mitigated ovarian aging phenotypes.

Project description:Female infertility syndromes are among the most prevalent chronic health disorders in women, but their molecular basis remains unknown because of the complexity of oogenesis and uncertainty regarding the number and identity of ovarian factors controlling the assembly, preservation, and maturation of ovarian follicles. To systematically discover such ovarian fertility factors en masse, we employed a mouse model (Foxo3), where follicles are assembled normally but are then synchronously activated. Gene expression profiling of mutant and normal ovaries led to the identification a surprisingly large set of ovarian factors. The set included the vast majority of known ovarian factors, many of which when mutated produce female sterility phenotypes, but most were novel. Subsequent analyses revealed novel classes of ovarian factors and significant overrpresentation on the X chromosome, among other insights into the general properties of oogenesis genes and their patterns of expression. Experiment Overall Design: Total ovarian RNA from +/+ and -/- ovaries at PND1, 3, 7, and 14 (n=3 replicates per timepoint and genotype, a total of 24 microarrays) was subjected to linear RNA amplification and hybridized to Affymetrix 430 2.0 mouse whole-genome microarrays, which interrogate >39K transcripts including the vast majority of protein-coding genes. We also profiled 14 somatic tissues. Additionally, to provide more refined views of gene expression, we profiled adult ovaries, adult testis, KitlSl/KitlSl-d testis (devoid of germ cells except for rare spermatogonia) (Shinohara et al., 2000), ES cells, laser-capture microdissected (LCM) primary oocytes, LCM somatic cells (granulosa cells + surrounding stroma), superovulated unfertilized eggs, cumulus granulosa cells, and E11 Foxo3 +/+ and -/- embryos. Each array data set was independently normalized by global median scaling, and the signal strengths were averaged for those samples for which replicates were available (PND1-14).

Project description:This batch of data is for three independent projects. Since in this three projects, the mouse strains are all CD1/ICR, the sex are both female, and the mouse ages are all two-month-old, three projects shared control data to save expenditure legitimately. But in our hand we couldn't segregate the raw data into two parts corresponding to two projects, so we uploads all raw data. However, we also provided researcher-analyzable excel files including the expression of all phosphorylated proteins. The concise description of these three projects are as follow: Project 1: We found that in Chronic Resistant Stress (CRS)-treated mice, the fertility and oocyte quality significantly decreased, and plenty of biochemical indexes significantly changed, so we guessed that the overall physical health of CRS mice was severely impacted. As one major strategy to investigate the mechanism how CRS impact the physical health, We chose TMT-labeled quantitative ovarian phosphoproteomics service from Hangzhou PTM Bio Co. We sent two repeats of two-month-old CRS CD1/ICR mouse ovaries and two repeats of control ovaries for characterization of differentially phosphorylated proteins. Each repeat contained about 60 ovaries from 30 female mice, about 300 mg. Project 2: We found that in High Salt (HS)-treated mice, the fertility and oocyte quality significantly decreased, and plenty of biochemical indexes significantly changed, so we guessed that the overall physical health of HS mice was severely impacted. As one major strategy to investigate the mechanism how HS impact the physical health, We chose TMT-labeled Quantitative ovarian phosphoproteomics service from Hangzhou PTM Bio Co. We sent two repeats of two-month-old HS CD1/ICR mouse ovaries and two repeats of control ovaries for characterization of differentially phosphorylated proteins. Each repeat contained about 60 ovaries from 30 female mice, about 300 mg. Project 3: We found that in arecoline (Are)-treated mice, the fertility and oocyte quality significantly decreased, and plenty of biochemical indexes significantly changed, so we guessed that the overall physical health of Are mice was severely impacted. As one major strategy to investigate the mechanism how Are impact the physical health, We chose TMT-labeled Quantitative ovarian phosphoproteomics service from Hangzhou PTM Bio Co. We sent two repeats of two-month-old Are CD1/ICR mouse ovaries and two repeats of control ovaries for characterization of differentially phosphorylated proteins. Each repeat contained about 60 ovaries from 30 female mice, about 300 mg. Two repeats of control samples and data were shared among project 1, 2 and 3. Gross protein levels were also examined and used to normalize the protein phosphorylation level.
